rev engineering IndexOutOfBoundsException

Hello:

I am trying the reverse engineering tools. I keep getting the exception generated below. I even download and installed the nightly build of the tools (HibernateTools-3.2.2.200807151612-nightly), and I still keep getting the same exception.

I can connect to the database and select the schema that I want correctly. hibernate.reveng.xml is included below as well. Any help is appreciated.

Hibernate version: 3.2

Full stack trace of any exception that occurs:

Exception while generating code
Reason:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Index: 0, Size: 0
<No message>

Name and version of the database you are using: postgres 8.3

hibernate.reveng.xml

Hi,

I had the same issue with postgresql 8.3 and I had as well issues with derby.

I finally ended up having an exact look at the supported databases: "Reverse Engineering support in database and drivers": http://www.hibernate.org/383.html

Now I'm working with hsqldb 1.8.0.10 which works fine so far.
So finally what you could do is to have a really lightweight hsqldb 1.8.0.10 parallel installation for the reverse engineering and generation and after generation work with postgresql.

Regards
Raoul

Hmm. I did check out that page and it said you should use a decent driver. I am using jdbc type3 from the postgres website. Is this considered "decent"?

How about a lower version of postgres? Perhaps 8.2?

Maybe try jdbc type2 and/or a lower version of postgres ...
Let me know if it works.
good luck

I tried postgres v8.2, with jdbc types 2, 3, 4, and I still get that error. Has anyone been able to successfully run reverse engineering on postgres?

what is the full stacktrace?

I havent tried postgresql in a while, it worked "at some point" though ;(

probably best to create a jira issue for it since you shouldnt get an AOOB exception in any case.
